The cornerboards on my house are made of 5/4 X 6 lumber. I have
replaced 3 of them with redwood and have no problem with those but the
rest keep rotting out on me. Redwood is no longer available. Are there
any synthetics that would work. I didnt see anything that Trex had
that would do the job.

I'd go with cypress or ipe.
